Military, medical & aerospace were the first exemptions granted - even the brain-dead arseholes who passed this crap know how dangerous lead free solder is!!!
Hmm... about that "some equipment used within an aircraft is within the scope"... are they referring to the equipment used to play the in-flight movies, or are they referring to the navigation equipment, transponder, equipment to activate the flaps, rudder, etc.?
Hmm, had a few beers, but, maybe we should **Insist** that
"servers, storage and storage array systems, network infrastructure equipment for switching, signalling, transmission as well as network management for telecommunications" must be lead free.
Why should something that just contains data be exempt
There seems to be unstated assumptions about the quality of domestic products over industrial products and life span.
Sorry, run out of neurons, OK the idea needs some work....Just inverting the argument can cause some "fun"
I've actually saw some tin coated boards with whiskers almost as bad as that. There are some pics on the net with whiskers over 1 cm in length. Also note that tin dendrite growth and tin whiskers are NOT the same thing.
The bigger problem, is that while industry sectors can get exemptions, it's becoming very difficult to get leaded components any more. Many vendors have simply dropped them. And we are now starting to see that many vendors will never be making new parts in a leaded option. So unless the aerospace manufacturers have hangers full of leaded parts, the exemption is no use. And even if they do have good stocks, they will be locked into 2005/06 technology.
Maybe the problem will be solved when the first Airbus full of Euro-crats crashes as a result of tin whiskers or tin pest?
You want to physically restrain the tin ? It's some kind of crystal growth so I doubt it'll be bothered by a coating. In nay case what you're suggesting is simply another band-aid on a truly bad idea.
There's plenty more problems anyway such as fatigue of the solder joint.
Haven't heard about Swatch ?
I'm sure there'll be screams of anguish eventually when the full implications come to light.

so I
is
Given the diameter of the whiskers, I doubt if they develop enough force to punch through. Strange phenomena anyway, because the whiskers don't start everywhere, but just here and there.
That's the one and only I heard off, and was mentioned here at SED about a month ago? One case is not much. I don't hear Philips, Sony, JVC, Samsung, HP, Canon, etc.
implications
The list of exemptions can be widened, if need be. I can imagine they add wrist watches to the list of exemptions, not much solder in a wrist watch anyway, so who would care about that kind of stuff being lead-free or not.
